SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 224,115, dated February3, 18 80.

Application filed October 23, 1879. Patented in Germany, June 19, 1878,and in Austria, October 14, 1878.

To all whom it may concern Be it known that we, JosEE THOMEE, of thecity of Kaschau, and FRANZ KoHAZY, also of Kaschau, in the Empire ofAustria, have invented new and useful Improvements in Locks forRailway-Carriages, of which the following is a specification, and forwhich invention we have obtained Letters Patent in Austria under date ofOctober 14,1878; in Germany under date of June 19,1878; and have filedapplications for Letters Patent in England on July 23, 1879; France,July 25, 1879; Italy, July 27,1879; Belgium, September 17, 1879; andRussia, beptember 18, 1879.

The object of our invention is to replace the usual seal of such locksby a controlling check or slip, which shall show the place and date, orthe place, date, and hour, where and when the lock has been closed oropened; and to that end it consists in a lock in which the locking-boltis liberated by the depression of the tumbler, said lock having achamberadapted to contain and hold a check-slip, said chamber being providedwith an opening for stamping or imprinting upon one part of said slipthe information of the closure of the lock, and an opening fordepressing the tumbler under another part of the said slip, and at thesame time stamp or imprint thereon the information of the opening of thelock, in combination with a key adapted to perform these various functions of stamping and opening the lock.

The invention further consists in certain details of construction, ashereinafter described, and as shown in the accompanying drawings, inwhich Figure 1 is a front elevation of our improved lock, showing thecheck-slip chamber open. Fig. 2 is a side elevation; Fig. 3, an interiorview of the front section of the lock; Fig. 4, a front view of the rearsection of the lock. Fig. 5 is a vertical transverse section taken online as m of Fig. 1, showing the key in position for opening the lock.Fig. 6 is a like view taken on line 2 z of Fig. 2, the key beingremoved.

' Fig. 7 is a horizontal section taken on line yy of Fig. 1. Figs. 8 and9 are an under-side plan view and a side elevation, respectively, of thekey; and Fig. 10 is a plan view of the check-slip.

Similar letters of reference are employed to indicate like partswherever such may occur in the above-described figures of drawings.

The lock is composed of two sections, the main casingA and the'backplate, 13, the former having in its interior suitable seats aa for saidback plate, the seat a forming, also, hearings for the fastening-boltsO. The casing A is furtherprovided with a bearing, a, at its lower endfor a third fastening-bolt, G. The face or front part of the casi n g isrecessed, and in this recess A fits closely a lid, I), hinged at d tothe lower end of the casing A. The inner face of the lid Dis recessed toreceive the check-slip hereinafter described, and has two openings, D D,a catch-hook, d, and a hand-hold or knob, d.

The back plate, 13, is provided with two projecting ledges, b b",between which is held and slides the tumbler E, and a bearingorshouldcr, b, that fits upon the seat a of the casing A. The backplate, B, also carries the pivot-pin F for the bolt 01' latch L, aguide-pin, E, for the tumbler E, and four retaining guide-pins, e, forthe four strong spiral springs E", which are seated in recesses b eformed,respectively, in the back plate and the tumbler, as shown inFigs. 5 and 6, the tendency of said springs being to force the tumbleroutward or away from said back plate, B, except when forcibly pressedinward, as hereinafter described. Finally, the back plate, B, isprovided with bolt-holes 11, corresponding in location with like holesin the casin g A, for the reception of the fastening-bolt O.

The tumbler E consists of a plate having its lower half of increasedthickness, to form the shoulder 0 across its face, and a recess, 6, onone side, which latter, together with the shoulder 6, forms arectangular bearing or seat, E, for the rectangular lower face, l L, ofthe locking bolt or latch L when the latter is locked by the tumbler, asshown in Figs. 3, 4, and 5. The tumbler E is further provided with aperforatedcylindrical boss or hub, E, projecting from the face of saidtumbler into a corresponding opening, A, in the casing A, and throughsaid boss passes the pointed guidepin E, the point of which projectsslightly beyond the face of the boss, which latter, in its normalposition, is flush with the recess A of the casing A, and forms abearing for the key, by means of which the tumbler is depressed forunlocking the lock, as hereinafter described. Within the longitudinalcenter of the recess A of the casing is formed ai'ecess, a, graduallyincreasing in depth or sloping toward the opening A, in which itterminates, for a purpose hereinafter described. The tumbler E isfurther held in position and guided by a pin, G, fitting in a groove, g,formed in the lower enlarged edgeface of said tumbler, and said pin orguidescrew G is secured to the lower hearing or ledge, I), of the backplate, B, as shown by Fig. 6.

Upon the lower front face, adjacent to the projecting hub or bearing 13,is a semicircu-' la-r tapering groove, 9, having its front edge, g,slightly beveled for the reception of the bolt H, which passes through abracket-bearing, h, on the side of the casing A. The outer end of thebolt has a square head, h, adapted to tit, when pushed inward, therectangular face of the bracket, which thus forms a lock for said boltto prevent its being rotated. The inner end. h, of said bolt is ofincreased diameter, forming a shoulder, which abuts against a likeshoulder in the opening through which said bolt passes, to prevent itsfalling out or being withdrawn entirely, the extent of motion of saidbolt outward being such that when fully drawn out the face of its innerend will be flush with the inner face of the casing A and out of the wayof the tumbler E.

Upon the inner face of the casing A, near its upper end, upon itsvertical center, is a sliding bolt, I, having at its lower end aprojecting and slightly beveled shoulder or bearing, 2'. It is slottedto receive the catch (1, and is held down or depressed by a spring orsprings, 1, except when pressed upward by the lockingbolt, ashereinafter described. The sliding bolt and spring are located within asuitable recess formed in said casing A, and held in proper position bya covering plate, i, as shown in Figs. 3 and 5.

"Upon opposite sides of the case A and flush with its front face areformed the lugs K K and K K, in proximity to the openings D D, said lugsforming bearings for the key when the slip or check is to be stampedafter closing the lock, or when the key is applied to open the lock, ashereinafter described.

L is the locking-bolt, having the form, in side elevation. shown inFigs. 3 and 4 and in dotted lines, Fig. 6, and in front elevation partlyin section, in Fig. 5, with the rectangular engaging-faces l and l,engaging with like bearingfaces 0 0 on the tumbler, the round head lengaging the shoulder on the sliding bolt I, the depression 1, and thenose 1. The bolt L is further provided with the engaging or lookingspurs or arms L, adapted to engage a hook or like device on the cardoorframing or on the car-door, according to where the lock is bolted, aswill be readily understood.

Referring to Figs. 5, 8, and 9, M represents the key, which consists ofa flat rectangular bar, m, of metal, the part M, that is pivoted to thefront end of said bar or handle m, and the follower N. The part M has ashank, m, the transverse arms m, and the arms m m The distance betweenthe latter is such that the part M may he slipped OVBI the casing A andits arms m m brought into engagement with the rectangular lugs K K or KK.

The bar or handle on of the key, near its front end, has a depending earor lug provided with a segmental slot, m, for the reception of apivot-pin, upon which is mounted one end of the rectangular bars a, andbetween the front end of the latter is pivoted the shank of the followeror plunger N, having a hollow cylindrical head, a, the front face ofwhich is provided with letters orn um bers, or both or any other desiredcancelingordistinguishing mark to be imprinted upon the check-slip Xwhen closing and opening the lock. The shank m of the part M of the keyhas a depending flat lug, which passes through the slot formed by thespace between the bars a, said lug on being provided with a flat head,M, upon which said bars slide when the handle m is depressed or elevatedto throw the follower or plunger N forward or back ward.

The operation of the lock is as follows: X is a check-slip, composed oftwo disks united together by a narrow strip, or, the whole stamped outof pasteboard, soft metal, or other suitable impressible and flexiblematerial, the diameter of the disks being such that one of them willclosely fit the recess d around the opening D, while the connectingarm90 of the disks will fit closely the recess d on opposite sides of theslit or opening D, which unites the openings D D in the lid D, and thelatter, fitting snugly in its recess in the casing A, will hold the slipX firmly in position except that portion of said slip which isdepressed, as hereinafter described.

This check-slip being placed in position and the lid D closed, the boltL is swung down to engage its arms L, or one of them, with a suitablelatch or fastening device, the bolt or pin H being drawn out, as shownin Fig.1. The diflerent parts of the lock will then be in the positionshown in Figs. 2, 3, at, and 5. The key M is nowplaced over the face ofthe look, so that its recessed arms m will be hooked over the lugs K Kand the follower over the opening D of the lid D, when the arm on isdepressed, and the follower forced forward to pass through said openingD and imprint upon the check-slip X the day, (late, and place when andwhere the lock has been closed, or such other mark as may be agreed uponfor that purpose.

If it is desired to open the look when the car has reached itsdestination, or at an intermediate point, each station being providedwith like keys, said key is now applied to the face of the look, so thatits recessed arms will be hooked over the lugs K K and the follower Nover the openings D of the lid 1). If said follower is now forcedforward onto the lower disk of the check-slip X, which lies upon thecylindrical boss E and the pointed guidepin E, the said boss will bedepressed, and when its bearing E, formed by the shoulders e and 0, hascleared the rectangular looking-faces l I, said bolt may be swung aroundon its pivot-pin F upward, and thismoveinent causes its rounded head I.to come in contact with the shoulderi of the slot-ted bolt I, press ingthe latter upward to release the catchhook d. on the inner face of thelid D, so that the unlocking of the bolt or the disengaging of said boltfrom its retaining devices by the depression of the tumbler and theupward movement of the said bolt simultaneously unlocks the check-slipchamber.

The opening of the lock by the depression of the tumbler performs stillanother function besides the unlocking of the check-slip chamber and thestamping of the lower disk of the check-slip Xnamely, the said checkslipis canceled by the act of depressing the tumbler, during which rearwardmotion of the tumbler the pointed guide-pin E is forced through thecheck-slip and passes into the follower N, and for this reason I providea hollow cylindrical follower .or stamp, N, and a recess ofgraduallyincreasing depth, a, within which the uniting-strip a: of thedisks of the check-slip X will lie when the tumbler is depressed. Thedepth of the recess a at the point where it terminates in thecylindrical opening of the casing is equal to the distance the tumbleris moved inward or backward.

It will be observed that this provision is an important one, as withoutit the lower disk of the check-slip X would invariably be severed fromthe shank a; when the follower N is forced inward or forward to depressthe tumbler, which is not desirable, as this would destroy the record,and would prevent the use of the other faces of the disk when the lockis opened prior to the arrival of the car at destination, which is oftendesi able.

If it is desired to use the lock simply as a fastening device, to beopened and closed at will without having recourse to the key, thetumbler is first depressed, and then the pin G is placed in positionrelatively to the bracket to permit of its being slipped inward into thesemicircular groove g in the front face of said tumbler, and the latteris then released, the pin holding it back out of engagement with thebolt L, which is then free to swing upon its pivot F, and when turneddown in a horizontal position the shoulder t on the bolt 1 will lie nearthe depression 1, at the lowest forward point of the rounded portion 1to permit the bolt Ito engage the catch (1 of the lid D; but when saidbolt is swung upward the rotation upon its pivot F will bring the higherportion of the head in contact with said shoulder i and push the bolt Iupward to release the catch, as already described.

To prevent the bolt L from moving inward with the tumbler, that part ofthe pivot-pin F upon which said tumbler slides is made of increaseddiameter to form the shoulder j, which forms a seat for said bolt andserves to hold it always in proper position, as will be readilyunderstood, and as plainly shown in Figs. 3, 4,

5, and 6.

It. will also be observed that the spiral or actuating springs E arearranged around and equidistant from the cylindrical boss E, whereby thepressure or power of said springs is applied uniformly.

We have described a tumbler having a cylindrical boss or hub, E, passinginto a corresponding opening formed in the casing, and a key having acylindrical head provided with alike axial opening. It is evident,however, that this precise form is notindispensable, nor is it necessarythat the openings 1) l) in the lid should be cylindrical, as any otherdesired form may be given to these partsin crosssection, the check-slipbeing correspondingly shaped.
